Answer:
The 5' and 3' polarity restriction
Explanation:
Discontinuous replication is when synthesis of new DNA molecule takes place as a series of short fragments that will subsequently be joined together.
These fragments are called the Okazaki fragments.
DNA synthesis takes place from 3' to 5' end. However due to 5' and 3' polarity. The replication has to be discontinuous due to the synthesis happening backwards and okazaki fragments being formed.
Mitochondria are the power plants of the cells.
Answer:
When an object experiences a net force, it will accelerate at a rate determined by its mass
Explanation:
A body at rest is considered to have a zero speed, so any force causing the body to move is an unbalanced force and any force causing the body to slow down is also an unbalanced force. An unbalanced force cause acceleration or deceleration i.e a change in speed
